P EX DING, C T G, Q3 N L NG- 0 4- App t on. le M rch 1.8- S r l .1 42 4To all whom it may concern:

Be it known that I, FREDERICK T. CON- LEY, a citizen of the UnitedStates, residing at Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements in PipeExpanding, Cutting, or 'Nurling Tools, of which the following is aspecification.

This invention has for its object the provision of a compactly arrangedand inexpensive hand tool for use in cutting, milling or expanding theends of pipes, being particularly designed for use by automobilists orothers who may be called upon to. make repairs to marine, steam or gasengines having small pipes in their organi zation. The present device isrelated to and an improvement upon or addition to the device shown in apatent granted to me Feb. 1 ,1919, No. 1,294,404.

In the accompanying drawings:

Fig. 7 is a detail view of the reamer,

The tool comprising my invention consists primarily of two body memberscrossed near their working ends and pivotally connected at the point ofcrossing by a boltv 1. The shorter portions of these body membersconstitute jaws 2 and 3 while the longer portions thereof constitutehandle members 4 and 5, the extremity of one of said handle membersbeing forked, as-

shown at 6, and provided with teeth or serrations 7 on one edge of thefork whereby it may be utilized as a wrench. The free ends of the handlemembers are connected by a screw or bolt 8 having a wing nut 9 mountedthereon and bearing against the.

outer face of one of the members, prefer: ably the member 4 which isprovided with the wrench or forked'portion 6. The opposite end ofthescrew or bolt 8 is pivoted to the, extremity of the handle member'5, and

a conical serrated or corrugated body 10, wh ch const tutes a reamer forlncreaslng the diameter of an opening or the bore of a tube, is securedto said member 5 at. the outer side thereof. The gripping jaw 2- carriesa webv 11 which may be secured thereon in any desired manner or formedintegral therewith and in the said web is mounted two or more rollers 12to engage against the side of the pipe upon which the tool is tooperate. The gripping jaw 3 is bifurcated and the edges of the membersofsaid jaw are serrated, as shown at 13, so that they will obtain afirmgrip upon the pipe placed between the jaws and hold it against'lative rotation as will be herein-. after set forth. A spring 14.- iscoiled around the, pivot bolt 1 and has its spaced divergent extremities15 bearing against the inner "faces of the handle members 4t and 5 sothat the said members and the gripping jaws are normally held apart orin open relation. When it is desired to cause the jaws to grip a. pipeor tube, the end of the tube or pipe is inserted between the jaws andthe nut 9 then rotated about the screw or bolt 8 so as to. swing theends of the handle members together which will obviously cause the jaws2 and3. to approach and bind against the pipe or tube so as to firmlyhold the same' Mounted to swing upon the pivot bolt 1 is a frame 16having a handle member 17 and a bearing arm 18, a screw 19 being mountedin the said bearing arm, as shown. This screw is provided with a conicalhead 20 which is adapted to enter the end of a tube or pipe held by andbetween the jaws 2 and .3, and as it enters the pipe, to expand the sameas more fully set forth in my aforesaid application, K

It will be readily observed, upon reference to Figs. 1 and): of thedrawings, that the handle members 4: and 5 are grooved on their innerfaces or substantially U shaped in cross section and the upper poretions of the jaws are bifurcated or slotted so that the members maycross each other and be piv'otally mounted upon the bolt 1. Pivoted uponthe bolt 1 and disposed between the members of the jaw 3 is the pipecutter 21 which is shown as a flat bar ha'ving its arms at oppositesides of its pivot point disposed at an angle to each other. The lowerarm 22 is housed within the groove or hollow portion of the handle menne ifi tiono l tters Pa ent- Patented Mar. 310, 19-20..

her 4 and to the lower end of said arm I' pivotally attach one end of anadjusting screw or threaded rod 23 which extends through an openingprovided therefor in the handle member 5 and is equipped at the outerside of said member with a wing nut 24 and at the inner side of saidmember with a lock nut 25. It will be readily understood that byadjusting the said nuts 24 and 25 the bolt or threaded rod 23 will becaused to move through the handle member 5 and, consequently, will swingthe arm 22 about the pivot bolt 1 so that'the upper member or arm 26will be caused to move toward or from the inner edge of the jaw 3 or thesur face of a pipe held between the jaws. The upper arm 26 of the lever21 is provided in one lateral face with a groove 27 in which is fitted achisel-like cutter or blade 28, the said blade or cutter being securedwithin the groove by a set screw 29 so that it will effectually resistthe thrust put upon it and i will remain in proper position relative tothe rod or tube being operated upon.

A circular frame 30 is mounted upon the pivot bolt 1 and is constructedwith an annular inwardly projecting flange 31 at its inner side whichfits against the inner face of the adjacent portion of the gripping jaw3. The cylindrical wall of this circular frame is constructed with aslot 32 through which the said member of the jaw 3 is passed so that theframe will move with said jaw and will remain constantly in concentricrelation thereto. Near the opposite end of the annular wall of thisframe is a groove or recess 33 which receives a turntable 34 and a capring 35 whereby the turntable is held in position. The turntableconsists of an annulus or flat ring provided with outstanding lugs 36 atdiametrically opposite points and having a handle 37 secured to orformed integral with the ring between the said lugs, the said handle, asshown most clearly in Fig. 4, being shaped to extend through the capring 35 and then extend radially from the turntable and circular frameso that the required turning movement may be impart ed to the table inthe operation of the tool. Flat sided screws 38 are inserted through thelugs 36 and to the inner ends of said screws are pivotally attached theends of links 39, the inner opposed faces of all the links beingserrated, as shown at 40, and the links attached to each bolt divergingfrom their pivotal connection therewith and having their ends remotefrom the bolts pivoted to the ends of the links extending from theopposedbolt, as shown at 41. A collapsible vise is thus provided whichis adapted to fit around the pipe or tube, indicated at 42 in Fig. 2,and securely clamp the same against all relative turning movement.Winged nuts 43 are mounted upon the bolts 38 and bear against the outerfaces of the will be readily understood. If it be desired to expand theend of a tube or pipe, the pipe is gripped between the jaws 2 and'3 andthe frame 16 swung about the main pivot or securing bolt 1 so as tobring the conical head 20 into axial alinement with the tube or pipe,after which the screw 19 is rotated in its bearing to cause the saidhead to enter the end of the pipe and thereby spread or expand the sameas previously stated. If it be desired to cut through a pipe so as tosever a section of any given length therefrom, the frame 16 is swungdownward out of the way and the pipe is then inserted through the linksor jaws 39 and between the gripping jaws 2 and 3 until the requiredlength .of pipe or tube haspassed beyond the cutter 28. The nuts 43 arethen manipulated so as to cause the link jaws 39 to firmly clamp thepipe or tube, as shown in Fig. 2, after which the adjusting screw orbolt 23 is caused to move through'the handle member 5 by manipulatingthe nuts 24 and 25 and the pipe cutter or lever 21thereby swung aboutthe pivot bolt 1 so that the blade 28 will be caused to bear upon thepipe or tube as shown in Fig. 2. The screw or bolt 8 then may bemanipulated so as to bring the jaws 2 and 3 into engagement with thepipe with just enough, force tov steady the movement'of the tool andprevent bending or twisting of the pipe but should not be so manipulatedthat the jaws 2 and 3 will bind upon. the pipe. The handle 37 is thenrotated about the axis of the frame 30so that the turntable 34 with thelink jaws 39 mounted thereon will be caused to move in a circular pathwithin said frame, thereby causingthe pipe or tube which is clamped byand between said jaws to rotate about its own longitudinal axis.Inasmuch as the blade 28' is biting into the pipe, a groove will be cutin the surface of the same and the cutter will be adjusted after eachcomplete revolution of the pipe so as to increase the depth of this cutand thereby gradually cut through the entire wall of the pipe so as tosever a section therefrom. After the pipe has been cut entirely throughso that the desired section will be severed, the link members 39 arereleased from the main section of the tube or pipe and the gripping jaws2 and 3 are also released so that the cut-off section may be removed andfitted where desired. The tool' may be also manipulated accomplish thisresult, the tube or pipe isinserted through the vise composed of thelink jaws 39 in the manner before described with the end of the pipe ortubedisposed between the gripping jaws 2 and 3 andthe cutter adjusted sothat it will not come into contact with the pipe. The screw or bolt 8 isthen adjusted so as to bring the jaws 2 and 3 into engagement with thepipe or tube so that the serrations 13 of the jaw 3 will bear firmlyagainst the pipe but will not bind or grip into the same. If theturntable be then rotated by means of the handle 37, the pipe will becaused to rotate between the jaws 2 and 3, moving easily upon the rollers 12, while the serrations 13 of the jaw 3 will scrape or wear uponthe surface so as to produce the desired roughening or mill- %rom theforegoing description, taken in connection with-the accompanyingdrawings, it will be seenthat I have provided a very simple, compact andinexpensive tool which may be carried in an ordinary tool box and whichmay be efliciently employed for a variety of purposes.
